In short
On August 9, 378, Roman emperor Valens led his Eastern army against Gothic refugees and their allies near Adrianople in what became one of Rome's worst military defeats. The Gothic forces, commanded by Fritigern, routed the Roman legions in a battle that killed Valens himself and roughly two-thirds of his 40,000-strong force. The catastrophe exposed the fragility of Rome's military system and marked the beginning of the end for classical Roman power in the West.
